AI Appraisal Estimate

This item is an olive or avocado green transparent glass vase featuring a bulbous base and a long, tapering neck that flares into a ruffled, asymmetrical tri-corner rim. The body displays vertical ribbing or optic molding that extends from the base through the neck. The appearance is stylistically consistent with mid-20th-century American art glass, specifically the 'swung' glass technique popularized by manufacturers like Viking, Fenton, or Smith. The piece shows a consistent green hue throughout with some natural light refraction highlighting the ribbed texture. No maker's marks, etched signatures, or labels are visible in the provided image, so a specific manufacturer cannot be attributed without physical inspection of the base for a pontil mark or signature. The glass appears to be in good condition with no visible cracks or large chips on the rim, though there is some light surface dust and minor internal streaking consistent with vintage pressed and swung glass production. The craftsmanship shows the characteristic irregularities of hand-finished decorative glass from the 1960s-1970s era.

Based on the provided imagery, I have examined this olive green swung glass vase, which exhibits characteristics frequently associated with mid-century American manufacturers such as Viking, L.E. Smith, or Fenton. From what I can see, the piece features a bulbous base and a classic tri-corner ruffled rim achieved through the swinging technique. The vertical ribbing is consistent with period production methods, though without a physical inspection of the base for a pontil mark or a surviving paper label, I cannot verify a specific manufacturer. The value estimate is based on the assumption that this is a vintage mid-century piece in good condition. Market interest for 'swung' glass remains steady among vintage decor collectors, with taller or more uniquely colored specimens often commanding higher premiums. My valuation reflects typical market behavior for items of this style and era; however, should the piece be identified as a modern reproduction or 'in the style of' rather than a period original, the value would likely decrease to the $20-$40 range. To establish a more precise attribution, an in-person examination is necessary to check for specific mold marks, glass weight, and UV fluorescence. Proving authenticity would require a side-by-side comparison with catalogued examples or documented provenance. The current estimate assumes no major chips or structural compromises are hidden by the photo's lighting or dust.
